What is the name of the tube that carries sperm to the ejaculatory duct?
the vas deferens
The vas deferens (also known as the ductus deferens) is a tiny muscular tube in the male reproductive system that carries sperm from the epididymis to the ejaculatory duct. There is a pair of these ducts in the male body, with one duct carrying sperm from each testis to the left and right ejaculatory ducts. Along the way they pass through the scrotum, spermatic cord, inguinal canal, and pelvic body cavity.
